To all 'whom t mag/concern: p

Be it known that I, Monms B. OKUN, a citizen of the United States, residing at Chicago, in the county of Cook and State new and useful Improvements.' in Bedstead-Corners, of which' the following is a specification, reference being had to the accompanying draw ings, forming a partthereof.

The purpose of this invention is -to provide an improved construction of corner fitting for a metall bedstead.

It consists in the elements and features of construction shown and described, as indicated in the claims.'

In the drawings z-Figure 1 is a perspective view of a bedstead corner Aembodying this invention, showing the angle iron side rail inserted with its horizontal flange at the top. Fig. 2 is a perspective view-fof a bedstead corner, showing the angle iron side rail inserted with its horizontal flange at the bottom. Fig. 3 is a longitudinal vertical section at the line, 3 3, on Fig. 1.' Fig.

4: is a section at the line 4-4 on Fig. 3.' Fig.

' 5, is a View similar to Fig. 3showingthe the preceding figures. Fi

side rail mounted inreverse 6 1s a detail section at the line, 6 6, on ig. 4. Fig. 7 is a perspective view of the. wedge fitting.

In. the structure shown in the drawings, the corner joint fitting comprises a housing', A, which is made from a single piece of sheet metal blanked out in proper form and folded in a manner which will be readily understood -'from Figs. l and 2 without specific descri tion, 'the resultin housing belng c substantie ly aA rectangular ox having one vertical edge shaped to seat against the bedpost, B, which in the drawing .is represented as cylindrical, requiring the fitting, A, to have its vertical edge which seats against the post correspondingly f concaved, as

and having the opposteedge apertured to receive the inserted end of the side rail, C, so that the latter will seat in the upper outer corner of the box. The side rail, C, made as usual of angle iron, has lone of its flanges cut back for a short distance which need not exceed two inches .at each end, reducing the width of that flange forv that extent to about one-fourth its full original width. This reduced flange' is indicated by the numeral, 3, in the drawings. The other flange for a distance, 3", at each end, corresponding to the length of the osition from reduced portion, 3, of the other'l'lange, is very slightly reduced, forming a shoulder, 3b, in the same vertical transverse plane with the shoulder, 3"', which resultsfrom the reduction of the other flange as described. Both of the flange portions, 3 and 3, are

`provided at their edges with one or more, (as

illustrated, two), notches indicated by the numerals, 4, 4 on the flange, 3, and la, 4, on the flange, 3a. These notches .are designed for' engagement of a locking and clamping device hereinafter described, and the pro-` vision of such notches inthe edges of both flanges, 3 and 3, and at both ends of the side rail, C, is designed Afor the purpose of adapting 'the rail to be secured in the housing either edge up,-that is, with the horizontal flange either at the top or at the bottom; and the provision of a lurality of notches in each of the flange e ges is designed for the purpose of adapting the rail to be engaged in the housing at as man different positions withV respect to its depth of intrusion into the'housing as there are notches in each ofthe edges. The two notches shown in each edge being spaced apart, say a dieV either to the depth of the first notch or to the depth of the second notch, tius rendering the bed frameadjustable to three differ-v ent lengths, the shortest length being obtained when the rail has both ends inserted to the depth of the innermost notch, the greatest length being obtained when both ends are inserted only to the depth of the outermost notch.

'For locking and clamping the rail in the housing, there is provided a wedge device, D, which is made of metal bar folded to form a three-sided or staple-like figure, the

'two legs, d, of the staple being-the wedge members, and the staple as a whole being adapted to be inserted up into the housing from the lower side at the outer end, so as to occupy the lower outer corner of the housing box with the longer vertical edges of the wedge side bars, 0l, bearing against the inner vertical side, A1, of the housing box, A, as seen most clearly in Figs. l and 5. The cross bar, d1, of the wedgel device, D, has a bolt-hole, d2, and a bolt, E, is provided adapted to be inserted' down through the boxI from top to bottom, said belt having a Isquare shoulder, E", adjacent to its head, and the hole for the bolt in, the top side, si?,

llO

of the housing box being squared to t this shoulder to prevent the bolt from turning. Said bolt extending down through the housing and out through the hole, d2, in the wedge device, D, is provided with a wing nut, F, screwed on to its lower threaded end for crowding the wedge device, D, up into the housing. In operation, the thumb nut is run down on the threaded end of the bolt sufficiently to allow the wedge devicemD, to drop its upper sloping edge low enoughto v admit the end of the rail, C, in either of the positions indicated; that is, with the horizontal flange either at the top or at the bot tom, as respectively shown in Figs. 4 and 5. The sloping edge of the wedge sides, d, is jogged or offset so as to constitute two separate slopes, d3 and d4, the latter 1n position to bind against the edge of the horizontal l flange when the rail, C, is inserted with that flange at the lower side, as shown in Fig. 5, and the latter, d4, being in position to engage the lower edge of the vertical flange of the rail when the latter is inserted with the horizontal flange at the top, as seen in Fig. 4. Preferably, and as the device is de signed to be customarily used, the rail, C, will be inserted into the housing a sufficient distance to bring one of the notches to the position for engagement by the edge of the wedge device when the latter is crowded up to wedging position, thus by the engagement of the edge of the wedge device in the notch insuring the rail against longitudinal 35, displacement. But whether engaged with the notch or with the edge of the rail between the notches, the wing nut, F, will be screwed up so as to crowd the sloping edges of both the wedge sides, ai, firmly against the edge of the rail, C, lodged on said sloping sides, whether it be the lower edge of the vertical web lodged on the slope, al, or the inner edge of the' horizontal flange lodged on the slope, d3.' `The width or distance between -the sides, (Z, of the wedge device, D, is preferably such that when the rail, C, is inserted to the utmost into the housing, both of said sides, cl, may be engaged with the notches, 4, 4, or 4a, 4; that is, the notches are preferably spaced in accordance with said width of the wedge device. It will be observed that notwithstanding the operation of the wedge device is to crowd the rail, C, up against the upper side, A2, of the housing box, it is not found necessary to specially ,fortify this top side against being bent up by the crowding. This is because in the first place the crowding action operates on the top, A2, of the box immediately in or adjacent tothe angle between said top and the outer side, and with minimum capacity, therefore, for bringing or bending it up; and, secondly, because this crowding action is effected by means of "abolt whose head in crowding isv bound down upon the top of the box at a point farther from the angle than'that at which the rail, C, is forced up against said top, so that the net effect of the clamping -action would, in any event, be rather to bend 7c the top down than to force it up. Such downbending isy of course effectually prevented by the lodgment of said topupon the upper edge of the innerI side wall, A1, of the housing box, and is further prevented by .a cross bar, C1, of the bd frame, which is an angle iron having itshorizontal flange bolted to a lug, A5, struck out from the inner side of the wall, A1, ofthe housingV box and its horizontal flange bolted to a so lug, a2, which projects from the inner edge of the top side, A2, of the box.

The housing box, A, is secured to the corner post, B, by means of bolts, G, having their heads inside the post, and which are therefore inserted from the inside of the post through the latterv and through bolt holes, a", in the back concavely curved wall or side, A6, of said housing box, the nuts being applied by means of a suitable key, entrance for which to reach the nut on .the upper bolt is provided through the forward wall, A, of the housing box by the curved notch, a7, in the inner edge of the rectanguv lar aperture which is provided in said wall ab for ladmission of the intruded end of the side bar, C. The nut on the lower bolt is accessible by such key inserted below the lower edge of said forward wall, A7.

In order to stifl'en the side bar, C, as much as possible against the danger of bending horizontally, to which it is exposed in handlingpthe bed bodily on the floor, the angle between the longitudinal and transverse 1 angles of the recess formed at the ends of the horizontal flange by cutting it back or narrowing it, as described, for insertion into the housing, is rounded as seen at 0X.

For guiding the wedge piece, D, accu-v rately into place and in its movement in its place when the thumb nut, F, is tightened to crowd said wedge piece against'the` edge of the side bar, lugs z3-a3 are struckinfrom the inner side wall, A1, of the housingsaid lugs being in a verticalline with each other 115 parallel with 'the forward wall, A7, of the housing against which the vertical edges, dx, of the side, d, of the wedge device bear and are guided in the insertion andvoperation of said wedge device.

For convenience of entering-theends of the side bar, C, into the housing, the corners of both flanges, horizontal and vertical, are slightly beveled, as lseen'at cy.
